KINEMATICS

in physics, change with time of the position or orientation of a body.

• Reference Point

• Rest

• Motion

• Gravity

This is the starting point or the origin of measuring motion.

• Moving object

• Reference point

• Finish Point

• Reference Object

The physical quantities which have only magnitude.

• Scalar Quantity

• Vector Quantity

• Direction

• All of the choices

The physical quantities for which both magnitude and direction.

• Scalar quantity

• Vector Quantity

• Acceleration

• Speed

All of the given choices are example of vector quantity except one.

• Displacement

• Acceleration

• Speed

• Velocity

is the total movement of an object without any regard to direction.

is defined as the change in position of an object. It is a vector quantity and has a direction and magnitude.

• Distance

• Width

• Lenght

• Displacement

gives only a quantitative idea about how fast or how slow an object is moving. The direction of motion is not considered.

This is the distance travelled by it in unit time in a given direction, or in other words, velocity is the rate of displacement of a body.

This is a change in its velocity. The change in the velocity of an object could be an increase or decrease in speed or a change in the direction of motion.
